n SPECIFICATION formingpart of Letters Patent No. 723,278, dated March 24, 1903.

Application filed April 26, 1902. $erial No. 104,806. (No model.)

To aZZ whom it may concern:

Be it known that I, EMILE ILG, a citizen of the United States, residing in the borough of Brooklyn, city, county, and State of New York, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a specification.

My invention relates to sewing-machines,

and particularly to that type of sewing-machine employed for sewing-goods together arranged at an angle.

My invention is particularly adapted for a sewing the edges and corners of satchels and other like articles.

I will describe a sewing-machine embodying my invention and then point out the novel features thereof in aclaim.

In the accompanying drawings, Figure l is aview, partly in side elevation and partly in vertical section, of a "sewing-machine embodying my invention. Fig. 2 is a detail elevational view withthe front plate of the bed removed.

Similar letters of reference designate corresponding parts in both figures.

The sewing-machine head is shown as consisting of a bed A and an arm A of ordinary construction.

The bed A is here shown as being substantially in the form of a hollow cylinder to accommodate the driving-shaft employed for operatinga shuttle mechanism A located in a recess provided in the end of thearm. y

A designates a throat-plate which is located, as usual, over the shuttle mechanism and is provided with the usual opening a for a needle to pass through to coact with the shuttle mechanism in forming stitches, and

with an opening a, through which a lower feed-dog A extends and works. The usual mechanism is provided for moving the feeddog to feed the material. .As shown, the lower feed-dog isin the rear of the needle-opening and is located close to the end of the arm.

A designates an inclined surface provided at the end of the bedA and in front of the shuttle mechanism, and Adesignates a plate located below the inclined surface A and secured to the bed A in front of the shuttle 5. j shown as consisting of a plate.

mechanism. The inclined surface A is here B designates a needle-bar carrying anceto the bonds or angles of leather dle b and having the usual vertical reciprocation. The means for producing its reciprocation may be of any suitable character in the art, and hence I shall not further describe or illustrate any. n

O designates an upper feed-dog which also has the function of pressing or holding the material onto the lower feed-dog and also assisting in the feed of the material. It is here shown as being in the form of a disk, which is rotatively mounted and provided with a beveled and knurled edge a. Any well-known mechanism may be employed for raising and lowering the upper feed-dog. n

It will be seen from the drawings that the needle is reciprocated in front of the feeding mechanism and that both the needle and feeding mechanism are located close to the edge of the bed in order that material arranged at an angle, as illustrated in dotted lines, may be sewed. It will also be observed that the material on which the feed mechanism acts is waste, and hence above the abjectionable marking of the feed mechanism on the goods which is common in other machines. It will also be seen that according to my invention there are incasing members for the lower stitch-forming mechanism, said members being provided with an upper face or throat-plate through which the needle and feed mechanisms operate and with an end face approximately upright and an intermediate inclined surface lying at an angle with both of said faces and extending into close proximity to the needle-hole. According to this construction seams may be formed close goods and other stifi materials to be stitched.

Obviously some features of myinvention may be used without others, and my invention may be embodied in widely-varying forms.

Therefore, without limiting myselflto the construction shown and described nor" enumerating equivalents, I claim, and desire to obtain by Letters Patent, the following:

In a sewing-machine, the combination with a tubular bed, of a throat-plate secured to theupper surface of the bed and having an opening for the passage of a needle in close proximity to its outer end, a reciprocating needle to work through said hole, a shuttle mechanism supported in the tubular bed plate having an inwardly-inclined upper porto codperate with the needle to form stitches, In testimony whereof I have signed my' said shuttle mechanism extending beyond the name to this specification in the presence of 10 front end of the throat-plate, and a plate to two subscribing witnesses. close the front end of the tubular bed, said EMILE ILG.
